Web/Android: Boxmeup is a new webapp and companion Android app that lets you pack a box, or container with items, enter the contents of that container into the webapp, and then print a QR code for it that can be used with your phone to pull up a list of its contents at any time.

If you move frequently, you may already have a system for this. In fact, we discussed a few iPhone-based QR Code solutions in our start-to-finish guide to moving to a new place. Boxmeup combines the best of both worlds, and lets you add the contents of your boxes or storage containers on your desktop, where it's easier to type, and then the app gives you QR codes to print and use to label your boxes. Scan the QR codes with the Android app, and you'll instantly be able to see what's inside.

This way you'll never have to stand in front of a pile of boxes after moving into a new place, wonder what's inside the one at the bottom, and have to move all of the ones on top to find out. There's no reason you couldn't use the app for entire storage units as well, with a QR code on the door or just inside that will tell you all of the contents of the space.

Update: Some of you have noted that this is more difficult than just typing up everything and writing or taping the list to the box. The point of using a QR code or some other label is privacy - meaning no one but you can tell what's in a box, minimizing the possibility of theft or loss. If it's more hassle than it's worth to you, clearly it's not a good solution for you. Your mileage may vary.
